Section 16 Serial Communication Interface (SCI, IrDA, CRC)
(2)
In reception, IR frame data is converted to a UART frame by the IrDA interface, and input to the
SCI.
When a high pulse is detected, 0 data is output, and if there is no pulse during a one-bit interval, 1
data is output. Note that a pulse shorter than the minimum pulse width of 1.41 µs will be identified
as a 0 signal.
(3)
Table 16.12 shows possible settings for bits IrCKS2 to IrCKS0 (minimum pulse width), and
operating frequencies of this LSI and bit rates, for making the pulse width shorter than 3/16 times
the bit rate in transmission.
